to produce a water sprinkler of the auto-.

matic type wherein the direction of the flow of water will be controlled automatically by. the force of the water leaving the sprinkler nozzle and acting upon a means externallyv of the nozzle for producing this A further object of this invention is to provide means for automatically causing the sprinkler nozzle to move in a clockwise direction and wherein there is also provided an adjusting means for varying the degree of movement in a clockwise direction of the nozzle and also causing the same to move in a counterclockwise direction.

With the above general objects in View and others that will appear as the nature of the invention. is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described in connection with the accompanying drawings and in which like characters of reference indicate similar parts throughout the several views.

In the drawings,

Figure 1 is a side elevational view of my device partly in section and partly broken away.

Figure 2 is an enlarged detail view of the mechanism carried by the forward end of the sprinkler nozzle for controlling the movement of the nozzle by the action of the water against said mechanism.

Figure 3 is an enlarged perspective view of my two-piece coupling collarwhereby the water inlet end of the nozzle member is rotatably mounted within a sleeve which carries an integral annular plate member rigidly attached to a support of the tripod type or the like.

Fi ure l is a detail view of the above mentioned sleeve and annular plate, said view also showing detachable means carried by the annular plate for controlling the degree of oscillatory movement of the sprinkler nozzle.

Figure 5 is a cross sectional view of a supporting clamp carried by the forward endot the sprinkler nozzle for supporting the water contacting plate which causes movement of the nozzle in opposite directions.

Figure 6 is a diagrammatical view of the water contacting plate showing in full and dotted lines the positions of this plate adjacent the outlet end of the sprinkler nozzle, said different positions being occasioned by the above mentioned detachable means carried by the annular plate of the coupling-collar, and

Figure 7 is a perspective view of my device in operation.

Briefly described, the present device con sists of a water nozzle of the connventional type rotatably supported in any preferable design of stand or support. For purposes of illustration, I have disclosed a support of the well known tripod type. Supported upon and in a horizontal plane with the outlet end of the sprinkler nozzle is a metallic water contacting plate. This plate pivoted. at its rear end to a support and is allowed a slight degree of movement as shown by dotted lines in Figure 6. The action of the water pressure striking against the opposite sides of this plate will cause the nozzle to move in a direction opposite to the side of the plate upon which the water contacts. For presenting the opposite sides of this plate to the action of the water pressure, I provide an arm operatively connected to this plate, which arm is relatively long and runs substantially parallel beneath the sprinkler nozzle. Detachably positioned upon the nozzle supporting structure, there is provided two vertical pin or lug members for alternately contacting with the extreme end of the trip arm. These pin or lug members may be positioned at any predetermined points apart for controlling the degree of movement of the nozzle. It will thus readily be seen that when the device is operating and the nozzle is moving to the right as'shown in Figure 7, the trip arm will strike against one of the vertical pins and cause the swinging plate to move across the path of the water for presenting its opposite face to the water pressure. This action causing the sprinkler nozzle to move in an opposite direction until the trip arm engages with the second pin on the supporting structure causing a reversal of the action.

Referring more in detail to the several views, there is shown sprinkler nozzle 1 having inlet and outlet ends 2 and 3 respectively. As a means for rotatably supporting the nozzle 1 upon a conventional type of tripod stand 4, I provide ribs 5 at the inner or inlet end thereof and surrounding the inlet end of the nozzle is a two-piece collar member 6 having corresponding ribs 7 adjacent its upper end. Bolted to the stand l, by theinedium of the bolts 8 is annular plate member 9 having a central axial opening'lO therein. Surrounding this opening and projecting upwardly therefrom is a sleeve 11 integral upon the plate 9 which sleeve receives the two-piece collar 6 and the inlet end 2 of the nozzle 1. The adjacent sides of the collar 6 and sleeve 11 are tapered as shown in Figures 1, 3, and 4: to provide a close fit between these members, and the collar is securely held within the sleeve by the thumb. screws 12. Adjacent the lower end of the twopiece collar 6, there are provided internal screw threads 13 "for detachably receiving the upper screw threaded end ota nipple 14-. The extreme lower end of the nipple is ribbed as at 15 for detachably receiving a suitable type of flexible hose 16 as shown in Figure 7.

Forwardly of the outlet end 3 of the nozzle 1, I have provided a swinging water contacting plate 17. As a. means for supporting the plate upon the nozzle 1, the nozzle is squared at 18 and is provided with an annular flange 19 upon its extreme forward end. Rigidly positioned upon the squared portion 18 of the nozzle 1 is a su porting clam 20 comprising jaws 21 and 22. Interemdiate the ends of each jaw member, tie same are cut away to provide a square opening 23 and as clearly shown in Figures 1 and 2, these jaw members are clamped upon the squared portion 18 of the nozzle 1 by the set screws 23.

The aforementioned swinging plate 17 is split at 24 efie'cting' side walls 25 and 26 and either welded or soldered therebetween is an upright rod 27. The upper end of this rod is forwardly bent at 28. and runs parallel with the upper edges of the side walls 25 and 26 of? the plate 17. This portion of the rod is likewise welded or soldered to the swinging: plate and projects a slight distance beyond the forward edge of the plate 17 into an elongated opening 29 formed n the jaws 21' and 22 of the supporting clamp 20. It will thus readily be seen that the swinging movement of the plate 17 Wlll be limited to the positions as shown by dotted lines in Figure 6. Screw threadedly mounted in the nozzle 1 at 30is an rear angular supper ting bar 31 which is braced adjacent its forward end within an angular opening 32 of the jaws 21 and 22 of the supporting clamp 20. Upon the forward end of the rod 31 is provided an enlargement 31' having a vertical. opening therein for receiving the upright rod 27 and de- 38 is adapted to alternately contact with these lug members for shifting the-plate 17 into dotted line positions as shown in Figure 6.
